All atoms of an element are alike and different from the atoms of all other elements. (com.ng)
Chemical combination takes place between small number of atoms of different elements. (com.ng)
Atoms of the same elements are alike but may differ in masses (isotopy). (com.ng)
A compound can only be separated into its constituent elements by chemical means. (com.ng)
The properties of compounds differ from the properties of the elements that make up the compound. (com.ng)
Being able to derive the correct whole number ratio of elements in a compound ensures students have a firm grasp of the law of definite proportions. (typecalendar.com)
Many students struggle with proportional reasoning and deriving the smallest whole number ratios of elements in compounds. (typecalendar.com)
The procedure can be broken down into several steps that include identifying elements, counting individual atoms, and counting atoms in compounds. (typecalendar.com)
The theory proposed and outlined by G. N. Lewis 1 gives us a definite picture of the structure of the atom for the elements in this simplified periodic table. (chemteam.info)
This works for compounds as well as single elements - 1. (slidetodoc.com)
The science of chemistry involves a study of these elements and of the compounds that are formed when different elements combine. (britannica.com)
Chemists also now know that elements are made of atoms . (britannica.com)
2) Atoms of the same elements have the same average masses, and atoms of different elements have different average masses. (britannica.com)
The two or more elements present in a compound are called constituents or components of the compound. (pw.live)
In general, a reverse chemical process breaks down compounds into their elements. (web.app)
A heterocyclic compound contains atoms of two or more different elements in its ring structure. (hawaii.edu)

They are also useful compounds in the synthesis of primary amines and amino acids for the application in the field of medicine and biological research. (chemicalland21.com)
